Walter,

Strictly from what I'm reading it sounds to me that your PCB has failed, or is failing. You will need to either;

1) Find your specific PCB (There will be a model number on the board itself) and order a replacement online, then install it on your own.

2) If you are not comfortable repairing it on your own, contact a local electronic repair shop and describe the problem as you've described it here and they will be able to further assist you.

Attached you will find an image of a common PCB layout.

Hope this helps,
Best regards.

I would try defrosting the fridge and then trying different temperature settings. It could be that the water isn't freezing early enough and water drips down onto the lever.

Yes you can do-it-yourself its sounds like the Back light led's in the back of the flat screen are not getting power. it could be 1 of 2 boards inside the chassis of the TV look online and put that model number in when you look.

Hi LakerFan, an LE code is generally a motor overload situation. A large comforter or a lot of bath towels will make the motor work too hard and start to overheat. Unplug the machine,hold the start button for 5 seconds and that should reset the error code. Hope that helps.

you either need a new one, or you need to fix the volume button so you can do a hard reset. Can you reset it via a computer like you can with an iPad I wonder?

Your water filter, if you have one installed, is located in the light housing of the top shelf. It is easiest to take your food off of the top shelf and remove the shelf to get easy access to it. I normally place a towel under it to catch any drips. If you do not see the canister hanging down then the bypass is likely installed. This is not a filter and can be used if no filter is desired. The "change filter" light will go off after a certain amount of time, or usage regardless if the filter,or bypass is installed.

bad display board or low voltage

Fixing and recharging air conditioners and refrigeration can only be done by licensed engineers. 'Freon' isn't used any longer, it R104 or similar. An engineer will use a spray to find where the leak is, fix it, suck out all the air, refill with Nitrogen, test for leaks again, then suck that out and refill with the correct number of pounds of refrigerant. It is the only way.
